【摘要】 研究目的:解决农用地分等以县或市(区)为单元进行空间数据结果汇总时,专题图层的边界位移和多边形的属性差异问题;对研究农用地分等中相邻图幅图斑界线的空间接边和图斑的属性综合问题。研究方法:运用地理信息系统(GIS)技术实现图形的“无缝接边”和属性综合法。研究结果:对农用地成果汇总中图层接边基本方法、程序和原则以及不同情况的具体接边技术,提出了相应对策。研究结论:基于Arc/Info等GIS软件的数字图层接边技术,不但可实现图形的“无缝”接边,同时能提高专题图接边的工作效率。更多还原

【Abstract】 The purpose of this paper is to discuss the measures of spatial edge match and attributive colligation between neighboring thematic maps of cropland classification. Geographical information system (GIS) method is used to realize edge match and attributive colligation without slot between neighboring thematic maps. The basic method, process and principle of edge match for map layers are put forward with GIS technique. The research results illustrate that digital edge match techniques of topic map based on Arc/Info GIS not only satisfy the requirements of edge match without slot, but also improve the work efficiency in edge match of thematic maps.更多还原
